Microsoft Setup Bootstrapper has stopped working while installing Office

Microsoft has tried to enhance installation of their products by implementing latest technologies. In the old days, we have used executable files which were quite capable of installing a product with a single click. However, in Office 2013/2016, Microsoft is using Bootsrapper technology. Bootstrapper is responsible for the initialization of an application built using the Composite Application Library. You can explore more about Bootsrapper technology on MSDN.

Recently, while installing Microsoft Office, we came around the issue of installation failure due to Bootsrapper technology. We received following error:

Microsoft Setup Bootstrapper has stopped working

A problem caused the program to stop working correctly. Windows will close this program and notify you if a solution is available.

Microsoft Setup Bootstrapper has stopped working

So as you can see in the error message shown above, Windows closes the program but it never notifies anything after that to solve this problem, and you have to manually fix it using following steps:

Microsoft Setup Bootstrapper has stopped working

Before you commence, please create a System Restore point before trying this solution. Since making mistakes in the manipulation of registry could result in messing up of your system.

Completely uninstall your Office installation. This is important. Having done that, now do the following and see if it helps.

1. Press Windows Key + R combination, type put regedit in the RunΒ dialog box and hit Enter to open the Registry Editor.

Mouse pointer sticks at edge while moving between multiple monitors in Windows 8

2. In the left pane, navigate here:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags

Microsoft-Setup-Bootstrapper-1

3. At this registry location, as shown in above image, right click over AppCompatFlags key and select Export. Save this key as registration file at a convenient location on your system for the backup purpose. Now right click the same key, i.e. AppCompatFlags and select Delete.

Microsoft-Setup-Bootstrapper-2

You can now close the Registry Editor and reboot the machine.

After restarting the system, you should install Microsoft Office, in Clean Boot State.

Let us know if you were able to resolve your issue following this procedure.

    Hi guys, I’ve had this issue too, it seems that this occurs when there are some remains from a corrupt office installation, i hope what I share will help you fix this…

    First things first, backup your registry, you can get steps to backup registry from http://support.microsoft.com/kb/322756

    CLEAN UNINSTALL
    1. completely uninstall office using fixit available on the following link http://support.microsoft.com/kb/2739501

    2. After completely uninstalling, RESTART your system.

    3. make sure your Admin account is enabled,

    Follow the steps to enable the Local Administrator on Windows:

    a) Press the Windows key to get into the Metro interface if you are not already there.

    b) Enter cmd and right-click on the Command Prompt result that should appear.

    This opens a list of options at the bottom. Select Run as administrator there.

    c) Accept the UAC prompt

    d) Enter the following command to enable the hidden administrator account:
    net user administrator /active:yes

    e) If you ever want to disable the account follow the same instructions, but run the following command instead:net user administrator /active:no ..

    you can also try and load office in clean mode, it does work, and please note that the steps i provided relate to windows 8

    This actually worked! Thank you thank you thank you

  14. e jay ali

    Everyone do not do what is shown above ,follow my steps.
    1. Go to task manager and disable EVERYTHING on startup,it is most-likely caused by a third party app you install with or without knowing the apply and close and you should be good (Don’t restart yet)

    2. Go to run (hold windows key and R) and type %temp% select everything and delete, then just type temp and also delete everything.Now go into recycle bin and fully delete it.

    3. Now restart and firstly try installing now , follow me on google plus if worked

  15. crusader

    hi it gives me an error cannot delete the registry when trying to delete the reg entry HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows_NTCurrentVersionAppCompatFlags. i have tried other things from other sites like renaming the %temp% folder and deleting all info in there. etc i have ran multiple Microsoft fixes but nothing seems to work. i think it is because i cant delete the reg key as described here. please advise.

    Dear All,

    Please dont do all these circus, just run setup.exe directly from Zipped folder without extracting..Installatiion will start..

  28. Marco Voli

    …. but fails after a while

  29. Marco Voli

    Use right click on the reg key, go to Permissions and give Full Control on it to Everyone.
    Then you’ll be able to delete it.
    But the bootstrapper error is still there for me.

  30. drcmda

    Amazing enhancement of the installation process they’ve managed to accomplish there. Really impressed. Having to hack around with the registry in 2016 and still NONE of the methods mentioned on this page work.

    I tried both ms office 2013&2016 to both errors
    previously i have windows 10 pro it works fine with both but not windows7

  35. bdone

    I tried all sorts of permission and ownership changes without success. I finally got it to work by using the following command

    close regedit if open, open cmd with psexec installed and run this:

    psexec -i -d -s c:windowsregedit.exe

    it let me delete the key, but this solution didn’t fix my problem with the bootstrapper not working right :/

    hi,
    Microsoft office 2016 professional plus installation error
    Microsoft Setup Bootstrapper has stopped working
    A problem caused the program to stop working correctly.
    Windows will close the program and notify you if a solution is available.
    following these steps are unhelpful to solve the above error.
